Step-by-step explanation:

A(-4, 5) => A'(-4+2, -5) = A'(-2, -5)

B(-6, -4) => B'(-6+2, -(-4)) = B'(-4, 4)

C(4, -4) => C'(4+2, -(-4)) = C'(6, 4)

Hence the new coordinates are A'(-2, -5), B'(-4, 4) and C'(6, 4).

3/x+2 = 2/x−1 pleasee help

olga_2 [115]

So you have:
$\frac{3}{x} + 2 = \frac{2}{x} - 1
$

1) Start off by multiplying both sides by x to simplify the problem:
$\frac{3}{x} + 2 = \frac{2}{x} - 1 \\
x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\
3 + 2x = 2 - x
$

2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
$3 + 2x = 2 - x\\
3x = -1$

3) Finally, divide by 3 on both sides to find the value of x:
$3x = -1\\
x = \frac{-1}{3}$

------

Answer: x = $\frac{-1}{3}$

What is the answer to -11b+7=40?

Andrews [41]

Hey there!

-11b + 7 = 40

SUBTRACT by 7 on each of your sides.

-11b + 7 - 7 = 40 - 7

Cancel out: 7 - 7 because that gives you 0

Keep: 40 - 7 because it helps us solve for our answer

40 - 7 = 33

DIVIDE both sides by -11

11b/-11 = 33/-11

Cancel out: -11b/-11 because it equals 1

Keep: 33/-11 because it gives you -3

33/-11 = 33 ÷ -11 = 3

Good luck on your assignment and enjoy your day!

5. AC bisects Angle BAD. Find the measure of angle BAC.

alukav5142 [94]

If AC bisects < BAD, it means it cuts it into 2 equal parts

so < BAC = < CAD

3x + 12 = 5x
12 = 5x - 3x
12 = 2x
12/2 = x
6 = x

< BAC = 3x + 12.......3(6) + 12 = 30 degrees <===
